[Conventional technology]

FIG. 4 is an explanatory diagram of a conventional data transmission system using telephone lines.

A telephone set 1 as a plurality of slave devices, and a detection means 2 for detecting a state change (for example, the occurrence of a fire) on the slave device side (for example, about 8 detection means such as a temperature sensor that reacts to a temperature change) are provided. ), inputting information from the telephone 1 and the detection means 2, and in particular, a speech synthesis means 3 for synthesizing speech based on the information signal from the detection means 2, and after performing various control processes. , a slave device side control unit 4 (for example, a microcomputer) that sends information (No. 3) to the subscriber telephone line, and an exchange that connects the line in order to transmit the information signal to the telephone 5 as the designated m device. vessel 6
It is composed of.

The operation of the above configuration will be explained.

For example, if a fire occurs in a place where the telephone 1 as a slave device is installed, one of the detection means 2 configured as a temperature sensor will detect the condition as the temperature rises, and the information will be transmitted. is output to the child device side control section 4.

Based on the fire occurrence information signal, the slave device side control unit 4 synthesizes the corresponding voice (for example, "Fire broke out at point A") using the voice synthesis means 3, and sends the synthesized voice to the subscriber telephone line as an analog signal. The exchange 6 then connects the line to the telephone 5 serving as the designated parent device.

The supervisor on the parent device side receives the message "
It becomes possible to perceive that a fire has broken out at point A through the synthesized voice saying, "A fire has broken out at the entry point." Through the above operations, it is possible to accurately notify the parent device of changes in conditions such as a fire at a predetermined unmanned place by voice. It becomes possible for the side to perceive.

[Problem that the invention seeks to solve]

However, in a conventional data transmission system using a telephone line, firstly, the voice synthesis means is provided in a control section on the side of a plurality of slave devices, which makes the control section on the slave side expensive. Accordingly, there is a problem in that the cost of the entire system increases. Second, since the information G transmitted from the control unit on the slave device side is simply connected to the telephone on the parent device side, if the supervisor on the parent device side is absent, the information G transmitted from the slave device side is There is a problem in that a device such as a so-called answering machine is required to record state changes or retain data in the control unit.

Third, there is a problem in that it is not possible to promptly respond to state changes on the child device side because there is no means to promptly transmit the status change information on the child device side received by the parent device side to a supervisor outside the home. There is a point.

[Means and effects for solving the problems] The present invention has been made in view of the above, and aims to reduce the cost of the entire system, ensure reliable information recording in the absence of a supervisor, and provide information to the supervisor. In order to enable quick information transmission and to efficiently and reliably transmit information changes on the slave device side, status changes on the slave device side are transmitted to the parent device side as digital signals, and audio is synthesized on the parent device side. The present invention provides a data transmission system using a telephone line that can record information and automatically transfer information to an absent supervisor.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a data transmission system using a telephone line according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is an explanatory diagram of a data transmission system using a telephone line according to the present invention. Telephone device 1 as multiple child devices
0 and a change in status on the slave device side (for example, a fire outbreak)
Detection means 11 (for example, it is possible to provide detection means for about 8 items such as a temperature sensor that reacts to temperature), information + a from the telephone 10 and detection means 11 are input, and various control processing is performed. After that, the slave device side control section 12 (for example, a microcomputer) sends out the digitally converted information signal to the subscriber telephone line, and the telephone device 13 as the designated parent device transmits the information signal. It consists of an exchange 14 that connects lines. In addition, the parent device side is provided with a parent device side control unit 14 (for example, a microcomputer), and inside the parent device side control unit 14, voice synthesis is performed based on digital information signals transmitted via the telephone line. The apparatus is further provided with a speech synthesis means 15 for performing the above-mentioned digital information signal, and a printing means 19 (for example, a printer) for performing printing processing based on the digital information signal. 16 connected to the exchange 14 is a pager calling/sending station, 17 is a pager, and 18 is a telephone set. (
Pager is a registered trademark of NTT. ) The operation of the above configuration will be explained.

For example, if a fire occurs in a place where a telephone device 10 as a slave device is installed, one of the detection means 11 configured as a temperature sensor detects the state as the temperature rises, and transmits the information to the slave device. It is output to the side control unit 12. Based on the information signal indicating the occurrence of a fire, the slave device side control unit 12 sends information to that effect in the form of a τ digital signal to the subscriber telephone line.
Connect the line to 3. The information signal received from the exchange 14 via the subscriber telephone line is input to the parent device side control section 14, and the parent device side control section 14 performs the control processing shown in the flowchart shown in FIG. First, when a digital information signal from the slave device side controller 12 is input to the parent device side controller 14 via the exchanger 14 (1), the parent device side controller 14 uses the internal The voice synthesizing means 15 synthesizes the voice (for example, ``a fire has broken out at point A'') (2), and records it. Next, the parent device side control unit 14 outputs a control signal to the telephone 13 to ring the bell of the telephone 13, and outputs a digital information signal to the printing means 19 to print out (3)
. When the telephone 14 rings a bell based on the output control signal and the supervisor picks up the receiver, (4)
The synthesized voice is output to the telephone set 13 to transmit the information VD (fire occurred at point A) to the supervisor (5).

On the other hand, if the receiver of the telephone 13 is not picked up because the supervisor is absent, and a predetermined period of time has elapsed since the control signal instructing the telephone 13 to ring, (6) The device-side control unit 14 outputs the registration number (telephone number) of the pager 17 stored therein to the subscriber telephone line (7). As a result, the pager call sending station 16 emits radio waves to the pager 17, drives the pager 17, and notifies the bearer of the call. The carrier perceives the call and switches the telephone 18 from the telephone 1.
When the line is connected to 3 (8), the parent device side control unit 1
4 outputs the voice previously created by synthesis to the telephone set 18 (9), and as a result, the carrier can obtain information that a fire has broken out at point A.

FIG. 3 shows another embodiment of the present invention, in which the child device side is
It is exactly the same as the one in the figure (the instruction numbers are also the same), but on the parent device side, the parent device side control units 14a and 14 are respectively
There are three telephones 13a, 14c (15a, 15b, and 15G are voice synthesis means), and three telephones 13a and 14c are provided.
, 13b, 13G1 printing means 19a, 19b, 19C are also installed.

With the above configuration, for example, when the slave device side control unit 12 transmits information to the parent device side control unit 14a, the parent device side control unit 14a has already received information from another slave device, etc., and the line is closed. If so, the child device control section resumes transmitting information to the parent device control section 14b. Furthermore, when the parent device side control section 14b is closed at 4°, information transmission to the parent device side control section 14C is resumed. This makes it possible to quickly transmit information by transferring it to another parent device even if the line is closed on the parent device side.

In the above embodiment, a case has been described in which three parent device systems are provided, but it goes without saying that the number is not limited to this number.

〔Effect of the invention〕

As explained above, in the data transmission system using a telephone line according to the present invention, state changes on the slave device side are transmitted as digital signals to the parent device side, and audio is synthesized and recorded on the parent device side. Since information can be automatically transferred to an absent supervisor, the cost of the entire system can be reduced, reliable information records can be maintained in the absence of a supervisor, and information can be quickly transmitted to the supervisor. This makes it possible to efficiently and reliably transmit state changes on the child device side.
